comma (01.259-4) i i .iiiy invention relates to paint mixingmachines, and the objects of my invention are;v u ,Firshto providea machine of this class which re-mixes canned paint without opening the can or removing the paint therefrom;

Second, to provide amachine of this class which is capable of mixingseveral cans of paint at a timer t i Third, to providea machineof this class which is small and compact as well as portable so that the machine may be installed in retail paint :storesor other places where relatively small quantitiesof paint are sold, thus enabling the retail purchaser to obtain his paint in as fresh, a condition and astwell mixed a, condition as if the paint: came'direct from the factory;

Fourth, to provide a machine; of this class which requiresylittle or no attention during the mixingoperation; 1 v 1 ,Sixth, to provide amachine of thisclasswhich isrsafe in its operation it. being .possibleito place acans-of paint upon the machine or removethem whetherthe 1 machine is in operation ornot, 1 and a Seventh, totprovide on the whole a novelly constructed paint mixing ;machine which is durable, .efiicient in its; action, and which will not readily deteriorate or; a get i out f order I With these and other objects in view as will appear hereinafterr my invention consists of certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon which form a part of this application, in which:

Figure 1 is a plan view of my paint mixing machine; Fig. 2 is a side elevational view thereof; Fig. 3 is a sectional view thereof through 3--3 of Fig. 2; Fig. 4 is a transverse sectional view thereof through 4-4 of Fig. 2, and Fig. 5 is an enlarged fragmentary sectional view through 55 ofFig. 1.

Similar characters of reference refer to similar parts and portions throughout the several views of the drawings.

Bed 1, link members 2, platform 3, rollers 4, motor 5, pulleys 6 and 7, belt 8, counter shaft 9, pulley 10, belt 11, flywheel 12, driven shaft 13, crank 14, yoke 15, bevel gears 16 and 17, drive shaft 18, ratchet wheel 19, pawl 20, lever 21, and connecting rod 22, constitute the principal parts and portions of my paint mixing machine.

A rectangular bed 1 is provided which is equipped with suitablefeet lit at its corners. Each comer of the bed 1 is also provided with upwardly directed lugs 1b each of which connects to thelower endof a link member 2. The upper ends of the linkmembers 2 are rotatably connected to; corresponding lugs, 3a which depend from the corners of a platform 3.; 1

The platform 3 is rectangular and approximately .the same size as the bedl. The ends of the; platform 3 are provided with upturned wells 3b which are provided with a series of slots-3c cut therein from their extended upper sides. flhe pairs of slots 30 form journals for rollers 4, the rollers being provided with stub- ;shafts 4a and; 4b protruding from the ends thereof {(0 sons to fitin the slots 3c, In the structure illustrated, four rollers are provided. These are arranged inparallel disposed relation. Each pair of rollers is adapted tov support one or more cans of paint, as shown best in Figs. 1 and 4.

[I'he platform 3 is adapted to oscillate back and forth withirespect to the bedl. Forthis purpose there is provided a motor 5 secured to the bed 1 which :is provided with a pulley 6 which is connected to another pulley '7 through a belt 8. The so pulley '7 is mounted upon a counter-shaft 9 which Iissupported above the bed 1 upon bracket bearings 1c. The motor 5 is positioned at or near one endof the bedl, whereas the counter-shaft 9 is positioned adjacent the opposite endof the bed. The shaft 9 protrudes slightly from one side of the bed 1 and is provided with a pulley 10 which is connected by a belt 11 to a flywheel 12, the flywheel 12 being provided with a belt receiving groove or channel 12m. The flywheel 12 is mountmo ed upon a shaft 13 which extends inwardly over the bed 1 and is supported relative thereto by a pair of bearings 1d. The inner end of the shaft 13 supports a crank 14 which may comprise a disk 14a which supports an eccentrically disposed pin or wheel 14b. The eccentric 14b engages a depending yoke member 15 which is secured to the platform 3. This arrangement causes the platform to rock back and forth with respect to the bed 1.

The cans of paint are positioned upon the rollers with their axes extending longitudinally with respect to the platform, hence the paint therein is caused to surge back and forth between the ends of the cans. In order that the paint can be com- 1 05 pletely stirred, particularly in cases where the sediment may have settled to one side or the other of the can, the rollers 4 are rotated with each movement of the platform. This is accomplished by means of bevel gears 16 secured to the 5:110

stub-shafts 4a of the rollers so as to protrude beyond one end of the platform 3. The bevel gears 16 engage bevel gears 17 mounted upon a common shaft 18 which extends transversely and in parallel relation with the corresponding end of the platform 3, the shaft 18 being supported therefrom by means of a plurality of bracket bearings 3d. The central portion of the shaft 18 is provided with a ratchet wheel 19 which is adapted to be engaged by a pawl 20. The pawl 20 is supported by a lever 21. The lever 21 is substantially U-shaped and journalled intermediate its ends upon the shaft 18. Its upper extended portion, designated 21a, carries the pawl 20. Its lower extended portion 21b is pivotally secured to a connecting rod 22 the other extremity of which is anchored to a post 1c protruding upwardly from the bed 1. Oscillating movement'of the platform 3 causes a rocking movement of the lever 21 andconsequently causes a partial rotation of the shaft 18 with each oscillation. y

In order to prevent damage to the cans of paint the rollers 4 are covered with rubber sleeves 40.

At any time whether the machine is idle or in operation the cans of paint whether large or small are positioned so as to be supported by pairs of rollers, the cans lying ontheir sides. The machine then gradually rotatesthe cansas they are shaken or oscillated back and forth. The rubber sleeves or coverings 4c are sufficient to prevent end movement of the cans of paint. However, if they should creep one way or the other no harm is done as they are retained-upon the rollers 4 by the end walls 3b. It is unnecessary to remove the bails provided on larger cans, however, the bails may be removed in order to place a larger number of cans upon the machine; it being here noted that the lugs or bosses from which the bails extend in no wise interfere with the-rotation of the cans as they readily ride over the rollers 4.

Though I have shown and described a particular construction, combination and arrangement of parts and portions, I do not wish to be limited to this particular construction, combination and arrangement, but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims. I

Having thus described my invention, what I claim as new and desire to secure by Letters Fatent is:

1. In a canned paint mixing machine for mixing paint in cans of various sizes, a support member, a plurality of links extending therefrom, a platform carried by said links, a plurality of paint can supporting rollers mounted on said platform, means for oscillating said platform with respect to said support member, and mechanism for periodically turning said rollers, whereby cans of paint carried by said rollers are both oscillated and turned.

2. In a paint mixing machine, a support member, a plurality of links extending therefrom, a platform carried by said links, a plurality of paint can supporting rollers mounted on said platform,

means for oscillating said platform with respect to said'support member, and mechanism including a ratchet and pawl element linking said rollers with said support member whereby movement of said platform causes said mechanism to turn said rollers.

3. In a paint mixing machine, a bed member, a plurality of links extending upwardly therefrom, a platform supported from the extended ends of said links, there being provided flexible joints between said links, bed member and platform, a plurality of parallel disposed paint can supporting rollers carried by said platform, means for rocking said'platform with respect to said bed member, and mechanism including a gear and shaft element carried by said platform, a ratchet and pawl means carried by said shaft, and a connecting rod associated with said ratchet and pawl and anchored to said bed member, whereby said rollers make a partial revolution during each move- "ment of said platform.
